Abstract
L'invention concerne une cellule de mesure de la conductivité de liquides. La cellule de mesure comprend deux électrodes extérieures opposées, une première source de courant, une électrode de référence et un voltmètre. La cellule de mesure comprend également une électrode perforée disposée amovible entre les deux électrodes extérieures ; une deuxième source de courant, la première et la deuxième source de courant envoyant respectivement un premier et un deuxième courant entre les électrodes extérieures et l'électrode perforée ; un dispositif de déplacement destiné à déplacer l'électrode perforée dans différentes positions ; et un dispositif de commutation destiné à commuter le premier et le deuxième courant entre les électrodes extérieures et l'électrode perforée. Les électrodes, les sources de courant, le voltmètre et le dispositif de commutation se trouvent dans un circuit. L'invention concerne également un dispositif de mesure de la conductivité d'un liquide au moyen de la cellule de mesure.
